3y^-4 × (2y^-4) = 6y^-8
= 6/1/y^8
= 6/y^8
.................................................
1) When x^1 multiply with x^2, 1 will add to 2 and become 3
= x^3
2) y^-1 = 1/y
3^-2 = 1/3^2 = 1/9

Answer:
11.95
Step-by-step explanation:
435 divided by 8 is 54.375
650 divided by 54.375 is 11.95 (Rounded)
Answer: No, the means in the two studies significantly is not different at the 95% confidence level.
Step-by-step explanation:
Since we have given that
Study 1,
Mean = 30.8,
Standard Deviation = 6.2,
Sample size = 100
And
Study 2
Mean = 32.2,
Standard Deviation = 5.4,
Sample size = 200
So, Hypothesis would be
So, At 95% confidence level, z = 1.96
So, the test statistic value would be
Since 1.96>-1.9228
So, we will accept the null hypothesis.
Hence,No, the means in the two studies significantly is not different at the 95% confidence level.
Start by placing the second equation in for Y so you have
2x+2(5+x)=10
Then distribute the 2
2x+10+2x=10
Then combine like terms
4x+10=10
Then subtract the 10 over
4x=0
Then divide the 4 and because 0 divided by 4 is 0
x=0
Then plug it back into one, Ill choose the second
y=5+0
Then add 5+0 and you get y=5
Your solution is (0,5)
